Novel rotary piston type engine

Abstract

The invention discloses a novel rotary piston engine which comprises an engine shell, a main transmission shaft and a piston group wheel; the piston group wheel is nested on the main transmission shaft; the main transmission shaft nested with the piston group wheel can be rotationally mounted in the inner cavity of the engine shell; the piston group wheel is composed of a rotary flywheel and at least a group of combustion chambers; the at least a group of combustion chambers are evenly arranged on the circumference surface of the rotary flywheel and on the same cross section; at least an air port composed of an exhaust port, a spark plug and an oil injection nozzle is arranged on the engine shell corresponding to the combustion chambers on the flywheel. Because the complicated crankshaft structure, the complicated cam structure and the complicated air distribution structure of the piston internal combustion engine are cancelled in the invention, the novel rotary piston engine has the advantages of more simple structure, higher fuel utilization rate, wide operation speed range, simple operation and control, good operation performance, ensuring the fuel utilization rate and the output torque to be in the best state.

Description

technical field [0001] The invention relates to the field of internal combustion engines (engines), in particular to a novel rotary piston engine. Background technique [0002] Existing internal combustion engine is divided into following several: several kinds such as reciprocating piston engine, rotary piston engine and gas turbine. [0003] If the reciprocating piston engine is classified according to fuel, it can be divided into gasoline engine, diesel engine and other types. Gasoline engine and diesel engine are the most widely used; according to the working stroke, it is mainly divided into two-stroke and four-stroke internal combustion engines. The internal combustion engine has developed from a simple structure, large volume and low power at the beginning of its invention in 1876 to today's modern internal combustion engine with a complex structure, small volume and high power, and has become an important power device in the world today. However, due to its structur...

Problems solved by technology

However, due to its working characteristics, it has poor operating performance, low fuel utilization rate, and high requirements for manufacturing materials.

[0006] Although the exhaust gas turbocharged internal combustion engine combined with a piston internal combustion engine and a gas turbine has recently improved its performance, it has a more complicated structure, higher manufacturing costs, worse reliability and durability.
